A term that is sometimes used in the context of uninsured motorists
(UM) and underinsured motorists (UIM) coverage to refer to the named
insured and the named insured's family members (as opposed to all
other insureds, referred to as Class 2 insureds). Class 1 insureds
may be afforded broader coverage than Class 2 insureds, especially
with regard to stacking of limits.
